TRACK-LAYING MACHINE.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed May 29.1907. fierial No. 376,895.

To all whom it may concern:

Be it known that we, WILLIAM MYRON SAXToN, lnrnn JAMES I-lnNsnLwoon, and ANDREW AUeUs'r JOHNSON, all subjects of the Kingof Great Britain, and all residents of Portage la Prairie, in the Province of Manitoba and Dominion of Canada, have invented a new and Improved Track-Laying Machine, of which the following is a full, clear, and exact description.

This invention relates to track-laying machines, and the object of the invention is to produce a machine of this class which can be operated by a small number of men to enable a railroad track to be laid.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation showing a short portion of track at the point where the construction is taking place, and illustrating the machine in operation; Fig. 2 is a plan of the machine as shown in Fig. 1; Fig. 3 is an end elevation of the machine upon an enlarged scale; Fig. 4 is a side elevation of the forward part of the machine, upon an enlarged scale, and showing a portion of the track in longitudinal section; Fig. 5 is a side elevation showing in detail the foot of a gallows frame which constitutes a part of the machine; and Fig. 6 is a cross section on the line 66 of Fig. 5.

Referring more particularly to the parts, and especially to Figs. 1 and 2, 1 represents a car, near the forward end of which a gallows frame 2 is erected. As shown in Fig. 3, this gallows frame comprises two vertical legs 3 which are connected near their upper ends by a cross brace 4. On the rear side of the gal lows frame and at a short distance above the floor of the car, a fixed platform 6 is formed.

At the right-hand side of the car a channel or tie train '7 is attached, andthis part operates as a guide for bringing ties forwardly in laying them. As indicated in Fig. 1, this tie train extends to a great dis tance ahead of the car and is supported by guy wires or braces 8 which attach to it by shackles 9 and 10 and lead upwardly to the top of the gallows frame. At the gallows frame these guy wires 8 pass over guide pulleys 11, and beyond these they pass downan inclined position and is attached to one of the guy wires 8.

The lower portion of the post 15 is provided with an inwardly projecting bracket 19 having a roller 20 adapted to support the rails when they are run out from the guide channel 13.

Near the right-hand side of the machine and on the forward end of the car 1, a long boom 21 is attached, and the free end of this boom is supported by a guy wire or cable 22 which is attached at its rear end to the upper portion of the gallows frame.

In the end of the boom 21 a guide sheave 23 is provided, and a similar guide sheave 24 is provided in the upper portion of the gallows frame.

Over the guide pulleys 23 and 24 a hoisting cable or line 25 passes, having a fall below the sheave 23, comprising a hook or grapple 26for holding a rail. The other end of this hoisting cable passes to a cylinder 27 where it is attached to the piston 28 which projects from the upper end of the cylinder as indicated in Fig. 4. This cylinder 27 is attached at the platform 6 on the rear side of the gallows frame, and a similar cylinder 29 is attached on the opposite side of the platform, as shown in Fig. 3. The piston 30 of this cylinder is connected by a hoisting cable or line 31 which passes upwardly through a guide sheave or pulley 32 which is opposite the guide pulley 24, and mounted on the under side of the brace 4 of the gallows. From this point the line 31 extends forwardly passing down through a guide pulley 32 which is mounted in the end of a short boom 33. This boom is similar to the boom 21, except that it is shorter as shown, and is mounted in a similar manner and its upper or free end is connected by a guy wire 34 to the upper end of the gallows frame as shown in Fig. 4. A guy wire 35 is provided, which connects the upper end of the post 1.5 with the upper end of the legs 3 so as to increase the rigidity of the dolly 14, as will be readily understood.

Beyond the sheave 32 the line 31 has a fall providedwith a grapple or hook 36 adapted to take hold of a rail 37 as indicated in dotted lines in Fig. 4. In laying the rails it should be undersood that they are run out through the dolly, as indicated in Fig. 4, and the grapple hooks 26 and 36 are attached just forward of the middle portion of the rail, whereupon the power is applied in the cylinders so as to raise the rail and allow it to swing into position in alinement with the rails already laid. During this operation it is only necessary for the gang of men to guide the rail, as its entire weight is supported by the boom 21 or 33 which supports the rail. Booms of different lengths are used in the manner described when the rails are being laid with break joints; that is, with the joints of one rail intermediate or staggered in relation to the joints of the opposite rail. If the rails are being laid with opposite joints, the booms will be of the same length. The cylinders 27 and 29 may be operated by steam or compressed air, connected by suitable pipes 38, in the latter instance, with an air reservoir 39; the said reservoir is kept supplied with air under suitable pressure from a compressor 40 mounted on the floor of the car as shown in Fig. 1. 1

Near the middle of the car 1 I provide an upwardly projecting frame 41 which operates as a rest for the gallows frame which may fold down upon the same in the manner indicated in dotted lines in Fig. 1. The gallows frame is normally held in an erect position by inclined braces 42 arranged as shown in Fig. 1. When these braces 42 are removed, the gallows frame may fold downwardly, for which purpose the lower ends of the legs 3 are attached to base plates 43 by means of suitable hinge connections 44, as shown in Figs. 5 and 6. Adjacent to the inner sides of the legs 3, vertical posts or stanchions 45 are fixed in the plates 43, and these support the aforesaid platform 6, and are connected by a cross brace 5.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. In a track-laying machine, in combination, a car, booms carried thereby and projecting forwardly, a gallows frame mounted on said car and adapted to fold down, a rest on said car adapted to support said gallows frame when folded down, said gallows frame having a pair of separated legs, a platform between said legs, cylinders carried by said platform, and hoisting lines operated by said cylinders and passing down over the ends of said booms.

2. In a track-layingmachine, in combination, a car, a long boom mounted on said car at one side and projecting forwardly, a short boom mounted on said car on the other side and also projecting forwardly, a gallows frame mounted on said car and adapted to fold downwardly, a rest on said car adapted to support the said frame when folded, said gallows frame having a pair of separated legs, a platform between said legs, cylinders supported on said platform, and hoisting lines operated by said cylinders and passing down over the ends of said booms respectively.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
